you should try running a Mcoy 8, it is a long body which that motor requires, you should also be getting more runtime than that also, we run that motor in oval and make 4 min easy, it is the same motor overall as the DYN 28, it is a good motor but the plug your using is not the coorect one, get a Mcoy and then retune and lean it out, 220 to 230 is good

No No. He is suggesting this plug here: http://www.amainhobbies.com/product_...um-Glow-Plug-1 The O.S. plug you have now is a short body plug. This engine needs the long body plug.

I have a buddy that ran this engine in his truggy off-road. It would pull wheelies at times, IN THE DIRT, and he pushed towards the 8 minute pit-stops with a little room to spare. Driving style has a big impact on fuel mileage.
